    • A micro electrostatic cooling fan arrangement is provided which includes a heat source having a planar surface, a stator attached to the heat source, an axle attached to the heat source and spaced from the stator, a rotary element including a hub having an aperture therein and a fan blade, the axle passing through the aperture of the hub and the fan blade having a major surface thereof disposed at an angle with respect to the surface of the heat source and attached to the hub at one end, with the other end of the fan blade being adjacent to but spaced from the stator and a voltage source applied to the stator having sufficient voltage to charge the fan blade.Also, a process is provided for making a microfan which includes forming a strip of sacrificial material on a planar surface of a heat source, applying a spin on insulating layer over the heat source and the strip for producing a sloping surface extending from about the top of the strip toward the planar surface of the heat source, applying a layer of conductive material on the sloping surface and strip and defining from the layer of conductive material a fan blade on the sloping surface of the spin on insulating layer and a stator at one end of the fan blade.
    • 提供一种微静电冷却风扇装置,其包括具有平坦表面的热源,附接到热源的定子,附接到热源并与定子间隔开的轴;旋转元件,包括其中具有孔的旋转元件, 风扇叶片,通过轮毂的孔的轴和风扇叶片的主表面相对于热源的表面设置成一定角度并且在一端附接到轮毂,而另一端 风扇叶片与定子相邻但间隔开,并且施加到定子的电压源具有足够的电压以对风扇叶片充电。 此外,提供了一种制造微纤维的方法,其包括在热源的平坦表面上形成牺牲材料条,在绝热层上施加旋涂在热源和带上,用于产生从顶部延伸的倾斜表面 的条带朝向热源的平面表面,在倾斜表面上施加一层导电材料,并且从导电材料层划分并限定绝缘层上的自旋的倾斜表面上的风扇叶片和一个定子上的风扇叶片 风扇叶片的末端。
